Compare header order and exact decoded row occurrences, then report records added to or removed from the second table.
Inputs are limited to 1 MiB, 10,000 rows, and 256 columns.

Strict, bounded, local processing
Row order does not affect equality, but duplicate counts do. The report separates header compatibility from row-level additions and removals.
A set would hide whether a row appears once or several times. This comparison counts each exact decoded row, then expands the count difference into added and removed record lists.
Header order is compared separately because the same row values under different headings do not represent the same record shape.
Cell matching is case-sensitive and whitespace-sensitive. The tool does not trim values, infer dates, round numbers, or choose a business key, because each transformation could conceal a meaningful difference.
